Galois automorphisms and blocks covering unipotent blocks

L. Ruhstorfer, A. A. Schaeffer Fry

In this paper we prove that a recent condition of Lyons--Martínez--Navarro--Tiep, regarding the field of values of extensions of characters in principal blocks, is satisfied for al…

The Isaacs--Navarro Galois conjecture

L. Ruhstorfer, A. A. Schaeffer Fry

We prove the original Galois refinement of the McKay conjecture, proposed by Isaacs--Navarro in 2002, providing an important subcase of the celebrated McKay--Navarro conjecture wit…

Towards the inductive McKay--Navarro Condition for groups of Lie type

Lucas Ruhstorfer, A. A. Schaeffer Fry, Britta Späth +1

We gather tools for proving the inductive McKay--Navarro (or Galois--McKay) condition for groups of Lie type and odd primes. We use this to establish a bijection in the case of qua…

The Alperin-McKay conjecture for the prime 2

Lucas Ruhstorfer

In this paper we consider the inductive Alperin-McKay condition for quasi-isolated 2-blocks of exceptional groups of Lie type. Thereby, we complete the proof of the Alperin-McKay c…

Quasi-isolated blocks and the Alperin-McKay conjecture

Lucas Ruhstorfer

The Alperin-McKay conjecture is a longstanding open conjecture in the representation theory of finite groups. Späth showed that the Alperin-McKay conjecture holds if the so-called…

Derived equivalences and equivariant Jordan decomposition

Lucas Ruhstorfer

The Bonnafé-Rouquier equivalence can be seen as a modular analogue of Lusztig's Jordan decomposition for groups of Lie type. In this paper, we show that this equivalence can be lif…
